What is the best store bought that anyone has found? Also I saw a sweet one being used at the Nationals top 8. I remember the guy using it said he built it with stuff he ordered off Amazon. I would really like one like he had.
Laser line for checking arc and obstacles
I got a Black and Decker laser level from Lowes for $15. Even came with batteries! Not the nicest one for sure, but definitely worth the money.
I have to say, this is a great idea and one I never thought of... needless to say I will be picking one up haha.
This one appears to be a firm favourite: Laserfuchs Line Tool
I've seen them used at tournaments here inthe UK... haven't been able to track one down myself yet though!

Be careful of etiquette and sportsmanship issues when using lasers. I think it's generally okay to use lasers when checking arcs or LOS when your own models are attacking. However I know some folks may be put-off if you repeatedly use lasers to do uninvited checks on shots they are calling. With lasers there's the danger of a slippery slope where flying casual flies out the window.

Weird.
As the opponent, you have an interest in making sure the shot the other player is calling is a legal shot. Laser pointers just help with that.

Just don't be an jerk. If the shot looks out of arc just politely say it. If he questions it just pull out the laser.

Yes but it depends...
Is it a very close call? I don't think anyone would have a reasonable objection. Pull it out every time, and it sounds like you just don't trust the other person.
Of course you also could have the issue where the other person actually thinks its out of arc, but says it is, and doesn't want you prove it's out.
Well, most arcs are easy enough to eyeball it or simply use the range ruler anyway.
It would only be if there were models in the way obstructing the use of a range ruler or a really difficult close call that a laser would be particularly useful. It does come up.
And of course, if it's your opponent attacking, the sporting and polite thing to do would be to offer to let them use the laser to check themselves.
After all, who wouldn't want to play with a laser? 
Laser levels are frickin' awesome. Seriously, everyone like them ...the techie stuff. Just no eye shots or airplane shots...
I use a laser in just about every game. It is ONLY used when the rules allow for measuring arc. There is nothing wrong in using it to double check your opponents arc when he's measuring his arc. In fact, once I tell my opponent that I have one, they often ask to use it while measuring 
If only there were sharks attached to them!
I need to buy me one of these!
Does anyone have a link to a decent laser level that they have used on Amazon.ca or Amazon.com? I'm looking for a Canadian distributor if possible. Preferably as cheap as possible.
Edited by AzulIn the south western US they have them at Harbor Freight. They are a circular saw attachment and run about $5, and include batteries. In case you are going to a Harbor Freight to buy one, they will be on the wall with the circular saw blades and attachments and in a yellow Blister pack last time I bought one.
As far as etiquette goes just fly casual. If it is really close even with the laser give your opponent the benefit of the doubt. In the shooting phase I see nothing wrong with checking the fire arc of everything you have. Sometimes you will see a shot that you didn't think possible. Also I always offer to let the opponent use the laser for arc they want to check from the beginning of the game.
The one Dukewolf suggested is great. I wish I had your directions when I went to buy mine, as it took forever to find it. Even the store clerks weren't aware they sold them. For $5 it is cheap, effective, and you can just take the small mounting off so you can hold it comfortably in your hand. Everything else I saw online ranged from $12-40. But these are small and can fit in any case.
Yep.... that's the laser fuch tool alright, re-boxed in a handy case! Thanks for the link!
This may be an unpopular opinion but I don't like laser-levels as an indication of arc. I find them to be just as accurate as the hand holding them freely in the air. Nothing beats a straight-edge in physical space for accuracy. Obviously the laser is useful for eyeballing but when it comes to true measurement its just not that good.

You say I will use ship A to shoot ship B.
I say I think it's out of arc, and you say otherwise.
Now what I've seen happens is we start measuring and using the range ruler one of the ships gets moved, just slightly.
So now which is it?
Even though it happened as an accident that one or two mm may make the world of difference.
So instead of debating and having the possible chance of hitting and accidently moving a ship with the ruler, use a laser.
If my opponent wanted to argue that is not tournament legal, I'd just say we'll this is a good tool to use so we don't move ships with the ruler.
The laser doesn't lie and we can both see it as clear as day
If he still insisted, then I'd say go ahead and let him line up the shot.
If he moved a ship by accident because of everything being tight together, then I'd call him on it.
Happens when I play my friends.
If I'm measuring arc and then I accidentally bump a ship then imo I feel as though I have to agree on my opponents behalf since it was I who now moved a ship and we can no longer tell
Even though I felt that it was 95% correct and he had no shot. Just for the fact that I now moved a ship it is no longer accurate and I have no say
Edited by Krynn007I'm the guy with the green super bright one from Nationals. It's two parts. I'll post details later, gotta get to an X-Wing event.
Awesome I have a Harbor Freight local....called and they have them in stock! HUZZAH!
Thanks Hexis! I really liked your setup.

Yup, I bought one of those, it works great.
